COMBINED HARBOW AND CULTIVATOR.

1 Application filed January. 26-, 1920.

Be it known that I, JAMnsi WV. MONT-V eoMnRY, a citizen ofthe UnitedStates, re-.

siding at Thomasville, in the county of Thomas and State of Georgia,have invented anew and useful Combined Harrow and Cultivator, of which.thefollowing is a specification.

This invention relatesto a combined harrow and cultivator, one of itsobjects being to provide a device of this character which will not dragor choke, and which, when in operation asa harrow, will cutgrass' andweeds under the surface; of the soil, there being an arrangement of soilengaging devices whereby the device can be used tov barr With theforegoing and other objects in View the invention resides in thecombina.- tion and arrangement of parts and 1n the detailsofconstruction, it being understood that changes in the precise embodment of the inventionherein disclosed can be; made within thescope ofwhat isclaimed without.

departing from the spirit. of the invention.

In the accompanying drawings the pre-" ferred form of the invention beenshown. 1

In said drawings Figure 1 is a bottom planview the machine. r

Fig. 2 is a side elevation. I

Fig. 3 is an enlarged section on line 33 of Fig. 1.

Referring to the drawings by characters of reference 1 and 2 designatesuperposed plates between which are extended parallel transverse crossstrips 3 each end portion of each strip being provided with alongitudinal series of apertures as indicated 'at 4;

To the upper strip 1 are secured brackets 55' from which are extendedhandles 6. These handles are suitably connected, as ordinarily, and areprovided with downwardly converging brace strips 7 receiving betweenthem the upwardly extending rear endportion 8 of a beam 9. A series ofopenings 10 are formed in the portion 8 and any one of them is adaptedto receive a-bolt 11 extend;

tom plate .19 and secu-red'to. the bottom plate 19 are metal strips 20,thev front ends of I which are inclined upwardly and forwardly.

A breastpla te' 21" is secured to the upward portions of the strips, oneof these breast plates being rotated at the front of eachof having slots22' for the reception of fasteningbolts 28 extending into the frontportlons of the strips 20. ii

Boltedlor otherwise secured to each breast plate 20 arethe shanks 24: ofnarrow. teeth 25,- the teeth extending downwardly below the level of theplate 19 as shownparticu- Secured oneachbottom plate a series of shanks26provided at the front ends "of the bottom plates 19, and eachbreastplate a say" rearwardly extending fingers .27 the rear portions ofwhichare twisted to form cutting blades 28, said blades'bei'ng diagonallydisposed so asto provide rearwardly diagonally arra'nged' cutting edges29'. The

blades 28 of each series are disposed oppositely to the blades of theother series and these blades can be positioned so as to convergerearwardly as shown in Fig. 1, or, un-

der some conditions, can be reversed or transposed so asv to divergerearwardly as o I 100 Bydetaching the yokes 17 fromthe yokes I I will beobvious.

16 groups of blades 28 can be quickly transposed. By means of the bolts15 and the series of openings 4 the series of blades 28 can be adjustedtoward or from each other. By providing the slots 22 the harrow. piece25 can beadjusted upwardly or downwardly relative to the bottom plates19, thus to regulate the depth of the out by the teeth. j

A bracket is'clamped on the beam 9 back of and close to the strips 3 andextends" l and; merge into abruptly inclined end porl pended fromdownwardly below the beam. The lower end of this bracket forms a yokeonwhichis mounted a pivot rod 31 on which spring fingers 32 arepivotally mounted, these fingers being spaced apart by sleeves 33 mountled on the pivot rod. The fingers are extended through a supporting plate3 f susably mounted are incllned' on the beam 9.

thus to increase or reduce the distance betweenthe points ofthe fingersand the surface ofthe soil. f

Forwardly converging brace strips 37. are connected to the cross strips3 and areat- V tached, at their front ends, to a bracket 38 secured onthe beam 9.

It will be apparent that when the device I is drawn forward the piece'25 will cut into the soil, the blade 28 will out under the surface ofthe soil, thereby severing the roots of weeds, etc. and at the same timedeflecting thewceds laterally toward the center of the The fingers 32with their end portions 36will operate' to tear the weeds out of theground and'to gather any loose l weeds that may be directed into thepaths thereof. 7 r

, What isclaimed is 1 1. The combination with a beam, a cross stripconnected thereto, and depending frames secured to the cross strip, of abottom plate secured to each frame, rearwardly extending blades carriedby each plate, said blades having obliquely disposed cutting edges, abreast plate adjustablyconnected to each bottom plate, and' mea'nscarried by a bracket 35 which is adjustof each ment of the machine, andmeans connected to the bottom" plate and extending rearwardly therefromfor making cuts transversely of said vertical cuts. i

3. The'comb'natlon with abeam and a cross strip connected thereto, ofbottom plates detachably and adjustably connected to the cross strip,rearwardly extending seriesof fingersupon the bottom plates,obliquelyextending cutting blades at the rear ends of the fingersandhaving their rearwardly extending edges sharpened, and meansadjustably connected to the front portions ofthe bottom plates forcutting downwardly into the surf face of the soil. l I

l. The combination with a beam, of'parallel transverse strips securedthereto, yokes adjustably connected to and depending from said strips,yokes the depending yokes, bottom plates secured to the detachableyokes, a breast plateupstanding from and inclined relative to eachbottom plate, said breast plates being adj ustdetachably connected to 7ably mounted, soil engaging feet-carried by the breast plates,rearwardly'extending obliquely disposed blades connected to each of thebottom plates, said liquely disposed cutting edges.
